Speedometer For a while it would randomly jump high or low. Over the weekend i drove it through 8-900 mile trip and the speedometer was jumping the majority of the time. I got in the engine and made sure all connected cords were tight and not lose. When I started the jeep again my yellow engine light came on. I took apart the dash to check out the connection behind the speedometer and it was in good condition. I followed the cords to the engine fuse box and the fuses were old but looked good. tw
